2) Two tiny conductingspheresare identicaland carry charges of -20 uC and +50 uC, respectively. They are separated by a distance = .025 meters A. Determine the magnitude of the force that each sphere experiences (4 points) and state whether the force is attractive or repulsive (1 point). B. The spheres are brought into contact and then separated to a distance of .025 meters. Determine the magnitude of the force (4 points) each sphere now experiences and state whetherthe force is attractive or repulsive (1 point). 3) A thick conductingsphericalshell (see figure) with inner radiusa = 0.02 m and outer radius b = 0.03 m carries a total net charge of +6 nC spread over its two surfaces. A point charge of size -2 nC is at the center of the conducting shell, and the conductoris in a state of electrostatic equilibrium. a. What is the electric field at 0.025m from the center of a spherical shell? 4
